Y BULKHEAD WALL FR CULVERTS.

- This invention relatesfto'metal bulkheads or retaining walls yforuse in conjunction with pipe culverts, such, for example, as the well knowncorrugated pipe culverts,and it has for its object to provide a simple and eicient device 'adaptedjfor attachment to the end of the culvert pipe section and Serving when in place, as a retaining wall for the dirt that is ordinarily piled upon said pipe.

It is a further object of the invention to provide a retaining structure of the character described, comprising a vertical end wall portion and a floor portion, the weight of the earth upon the floor aiding in holding the end wall in place. y

Further objects and advantages of the invention will be set forth in the detailed description which follows.

In the accompanying drawing:

Fig. 1 is an outside view of a-bulkhead constructed in accordance with the present invention. A

Fig. 2 is a plan view thereof and Fig. 3 is a vertical sectional view upon line 8 3 of Fig. 2.

Like numerals designate corresponding parts in all of the figures of the drawing.

In the drawing, 5 designates a portion of a corrugated culvert pipe of well known form. The bulkhead comprises two sections and each section comprises a vertical wall 6 and a floor 7 The vertical floor and wall may be made of separate pieces butted to r gether in any well known way, as by welding, for example, (see Fig. 3), or they may be in onerpiece. The vertical wall portions 6 are complementally cut out at 6a to fit about the vculvert pipe 5, and the two sections are drawn into engagement with each other and with the culvert pipe, bymeans of bolts or like fastening devices 8, which pass through ears 8a of straps 9, said straps being secured to the respective vertical walls 6. The walls 6 are 'reinforced by channel irons 10 and the floor sections are reinforced by channel irons 11. Braces 12 have hooked lower ends 13 which are adapted to pass through openings 14 complementally formed in the floor sectionsand the channel irons 11 thereof, while the upper ends of the braces have threaded ends 15 that are adapted for engagement by nuts 16 and 17. The threaded ends of the braces are passed through suitable openings 18, complementaily formed in the vertical Walls 6 and in the vertical channel irons `10, and after the braces are put in place they may be secured against dislodgment and firmly tie the walls 6 and floors 7 into substantially right angular` relation to .each other by .the tightening of the nuts 16 and 17.

It will be apparent that the weight of the dirt, piled about the culvert pipe and resting upon the Hoor 7, will tend to hold said floor in place and provide an anchorage for the inner ends of the braces and that this in turn provides an anchorage for the upper 'i portions of the walls 6, due to the location of said braces. This, in conjunction with the fact that the two sections of the vertical walls of the abutment are bound into engagement withthe end of the pipe by the drawing of the same toward each other,

renders the whole structure an exceedingly rigid one, and one which will efficiently serve the purpose of holding the dirt in place at the end of the culvert pipe.

It is to be understood that the invention is not limited to the precise construction set forth but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims.

Having described my invention what I claim is: Y

1. A bulkhead wall of the character described made in two sections, each of ysaid sections comprising a vertical wall` portion and a floor portion,the confronting edges of said wall portion being complementally cut out to fit about a culvert pipe, means for drawing said sections toward each other to bind them upon a culvert pipe, and braces engaged with said floor portion and said wall portion.

y 2. A structure as recited in claim 1 wherein said braces are provided. with hooked portions at one end and nuts and threads at the other end.

3. A bulkhead retaining wall of the character described formed in two parts, each yof said parts comprising a vertical wall portion and a horizontal floor portion, braces extending between said Hoor and wall portions and means for drawing said wall portions toward each other` and about a culvert 1 e. f p A structure as recited in cla-im 3 in combination with reinforcing members extending vertically along the Vertical Wall portions and horizontally along the Hoor portions, said braces engaging with said reinforcing members.

5. A structure as recited in claim 3 in combination with braces extending Vertically along' the Wall portions and horizontally alongl the iioor portions and braces having hooked lower ends which pass through the l reinforcing' members of the floor portions and threaded upper ends Which pass through the reinforcing members of the Wall portions and nuts upon said threaded ends, both in- Wardly and outwardly of the Vertical Wall portions.

6. A bulkhead Wall of the character described rnade in two sections, each of said sections comprising a vertical Wall portion and a substantially horizontal floor' portion, the confronting edges of said Vertical Wall portion being complementally cut out to vfit about a culvert pipe, and means for drawing the said two sections bodily toward each other and into tight engagement about the culvert pipe, the said cut out portions being located at such point that When engaged about a culvert pipe said pipe Will overlie the iloor portions of the sections.

In testimony whereof he aiiixes his signature. i v
